Thanks. I tried doing this and the list didn't update:
void AddToList( SList!int list, int i )
{
list.insert( i );
}
SList!int intList;
AddToList( intList, 42 );
but when I switched to this, it worked:
SList!int intList;
void AddToList( int i )
{
intList.insert( i );
}
AddToList( 42 );
The first method didn't give an error it just didn't update the
list as I thought. Any idea?

~= because it works fine for arrays but apperantly not for

How do I add an element to a list?
import std.stdio;
import std.container;
void main()
{
auto l = SList!int();
l.insert(42); // inserts front
l.insert(43); // this too
assert(l == SList!int(43, 42));
// inserts after the specified range (l[] is the entire
list)
l.insertAfter(l[], 44);
assert(l == SList!int(43, 42, 44));
// This doesn't work because SList.Range doesn't define
opOpAssign!"~"
// l[] ~= 45;
}
